Application :tiled April 21, 1913. Serial No. 762,483.

To all whom it may concern: Be it kno-wn that I, Louis M. CARL, a citizen of the United States, residing in Chicago, in the county of: Cook and State of a new and useful Im- Window Constructions, of

specification. to improvements in provement in which the following is a This invention relates window construction.

One cbj ect ot the invention is to provide a window construction in which the slidable sashes are adapted to swing outwardly around horizontal axes and about pivots carried by the sashes.

Another object of the invention 1s to promay be readily attached to the ordinary slidable window sashes now in use to adapt the same to be swung out from the window Jframe.

rIhe invention furthermore consists in the improvements in the parts and devices and in the novel combinations of the parts and devices as herein shown, described or claimed. Y

In the drawing forming a part of this specification, Figure 1 is an outside elevation of a window embodying my improvements; Fig. 2 is va vertical. sectional view taken on the line 2-2 of Fig. 1, the window sashes being omitted except as shown in dotted line to indicate the position to which the sashes are swung; Fig. 3 is a transverse, sectional view taken on the line 3-3 of Fig. 1; Fig. Ll is a detail broken view, partly in section and partly in elevation, to illustrate the means forming the pivots and showing also the method of attaching the weight cords; Fig. 5 is a detail sectional view taken substantially on the line 5--5 of Fig. 4:; Fig. 6 is a detail sectional view taken substantially on the line 6-6 of Fig. 2 and Fig. 7 is a detail sectional view taken on the line- 7-7 of Fig. 6.

In the drawing, the window frame is designated. generally, by the reference A, and, as shown, is provided with the usual orm of grooves 10, 10 separated by a partition or parting strip 11, to form suitable guides for the upper and lower window sashes 12 and 13. A portion 14 of the inner strip for confining the lower window sash 13, on each side of the frame, is made removable by means of screws 15 to thereby permit the insertion and removal of the sashes, and also to permit the outward swinging of the latter,

upper sash 12 is pushed as will be hereinafter described. The sash pulleys 16 are provided, as shown in Fig. 2, over which run the weight cords 17, the latter being attached to the sashes, as about to be described.

Each of the guide-forming grooves 10, is provided with a slot in which the weight cords 17 are adapted to take and in which also slide the pivot-forming cylindrical sleeves 18, through which the ends of the cords 17 are passed. as shown more particularly in Fig. fl, and held in place as by means of knots on the ends thereof. Each pivotiorming sleeve 18 is loosely rotatable in a bearing 19, the latter being secured to the lower face of the sash in a suitably formed recess 20, the lower face of said bearing member 19 being iiush with the lower :tace oi the sash. In order to prevent the pivotiorming sleeves 18 from being pulled outwardly by the weight cords 17. they are each provided with an inner shoulder 118 engaging the bearing member 19. Each pivotorming sleeve 18 is also provided with a recess 21 on its upper face through which the weight cord 17 passes. Each sash is provided on its side edges with'slots or rabbets 22 adapting the sashes to pass by the pulleys 16 and also Jforming pockets into which the cords 17 may be pushed during the raising and lowering ot' the window sashes.

In operation, whenever it is desired to swing the window sashes out from the frame, the members 14; are removed and the lower sash 13 swung out about the pivot-forming sleeves 18, the latter being` held down in place against the action of the weights by means ofsliding locks 23, one on each side of the window trame, each sliding lock 23 beingmounted in a suitable guide piece 24', secured to the window frame, as shown in Figs. 6 and 7. After the lower sash has rbeen swung out, as above described, the down and swung about the pivot-forming sleeves in its lower edge, the upper sash being held down against the action of the weights by sliding locks 123 mounted and operated similarly to those referenced 23. During the outward swinging of the sashes, it is necessary to provide a small amount of clearance for the outside lower corner edges of the sashes, and for this purpose notches 25 are provided in the sides ot the trame in which the pivot 3o th ormingsleeves 18 are free to move during the swinging movements of the window sashes. During the swinging movements of the sashes, the pivot-forming sleeves 18 will turn in the bearing members 19 on account `of the weight cords 17, which will always maintain the sleeves 18 with their openings 21 facingupwardly.v

From the preceding description, it will be seen that the pivot-forming devices which I have shown and described, are readily attachable to forms of slidable window sashes now commonly in use, that the pivot-forming devices are practically concealed from View, and that the slidable sashes may be swung out about horizontal axes to the positions shown in dotted lines in Fig. 2, by merely removing the members 14 and throwing in the locks 23 and 123.

The ends of the sash cords are inserted into'theapertures or recesses 20 and the locking orf pivot-bearing forming devices 23 extend across the cords in effect to prevent the endof the sash being pulled upwardly by the counter-weights. .The sleeves 18 constitute i'n ei'ect protective coverings for so much of the window cords as would oth I-n letting the cords into the sleevesth rough le openings in their cylindrical surface, the

be made in the details of arrangements of parts v from the spirit of the invention, andall such changes andvariations are contemplated as come within the scope ofthe claims appendedY hereto.

lower sash when the latter is in its lowermost position. This is done in order to pro` vide clearance for the upper sash when the latter is being swung out from the frame.

I claim 1. A window construction frame having guides for adapted to permit a sash mounted therein to be swung inwardly when in lowered position, a sash mounted in said guides, sash cords and weights, hollow sleeves rotatably positioned in said sash near its lower end, the ends of said cord being secured in said sleeves, said sleeves forming pivots about which said sash may move, and pivot-bearing members for engaging said sleeves between the cords and adjacent surfaces of said sash. t

2. A window construction comprising a frame having guides for a window sash and adapted to permit a sash to be swung inwardly when in ,lowered position, a sash mounted in said guides, sash cords and weights, the ends of said sash cords being inserted within apertures provided in the sash for their reception, retaining devices adapted to be projected above said sash cords where they enter the sash and when the sash has been lowered and swung inwardly, and metallic sleeves surrounding said sash cords to protect them from said devices.

v3. A window construction comprising a frame having guides for a. window sash and adapted to permit a sash mounted therein to be swung inwardly, a sash mounted in said guides, sash cords, and means for securing the ends of said sash cords in said sash, each of said means comprising a bearing provided in the sash, and a hollow sleeve closed at its outer end and having an aperture through its cylindrical wall, an end of said cord being disposed through said aperture and extending inwardly of said sleeve and of the bearing.
